Make sure they are the same if you can’t see them look at the number of stars or dots. Look at the mail server settings boxes for password and port settings they’re the ones you need to delete and reapply. Doing a send and receive manually or waiting on the scheduled send and receive on the client does not update new mail items.

Furthermore, when calendar invites are accepted using the Outlook client, they disappear from All Mail and go into the Trash folder, but when using WebMail, they remain in the Inbox. I have seen this disparity for years across different Outlook client versions and Windows versions. I also posted on how to fix Outlook Not opening Today the Gmail subreddit about a year ago.

I have several email accounts / IMAP set-up. So looking at my tree of troubleshoot Outlook synchronizing folders error email accounts one inbox might have 10 mail total and 3 unread form earlier. It's not until I click on that folder I will then see the 10 and 3 and two second later it will sync and new ones will populate. The issue is; just looking at my email accounts and the numbers shown next to the folders I cant tell if there is new mail or not until I click on them.

Chosen solution

I don't see - 'When getting new messages... I checked all 5 of the tabs in this window that expressions is not there. This seems bizarre the email would not populate. The uploading of the old messages to the new account is what caused the problem. I will try the safe starts and experiment with the buttons ans see if it improves.

My accounts in Mail app stopped to sync post update

I am using TB for just three weeks now and I have issues daily troubleshoot Outlook synchronizing folders error when sending mail with no attachments the outgoing mail server will time out. Since the sync issue is universal it appears to be a global issue. Perhaps something in TB needs to be tweaked. I have no firewall monitors running during the day that would interfere just the vpn. With that said - the "delayed syncing" issue that I am experiencing is happening on Inbox as well as Junk folders.





While outlook supports IMAP, it doesn’t really want to work with it, so not surprised you are having some troubles. My phone, which I have no problems with, is behind the same router/firewall as the PC on a regular basis. The issue persists with PC connected directly to the internet with no router or firewall in between.

• This limits the amount of network traffic and improves performance for syncing important folders.
• We only have a handful of people who use the their email across multiple devices at the corporate office.
• Furthermore, when calendar invites are accepted using the Outlook client, they disappear from All Mail and go into the Trash folder, but when using WebMail, they remain in the Inbox.
• These methods help you in the synchronization process.
• Full cleanup of ALL accounts is not a solution(and re-add even helps not).
• Look at the mail server settings boxes for password and port settings they’re the ones you need to delete and reapply.
• From what I’m reading, this doesn’t actually appear to be an issue with receiving email, it’s an Outlook screen refresh issue, or possibly (although less likely) an issue with notification settings.
• I went to a bunch of online TLS tests and the mail server is fine and the certificates are trusted...

I did see a response from a MS person that said it was working as intended, that it wouldn’t refresh the folder until it was selected. Although that seems like a load of BS, but could just be a con to try to migrate people to exchange at a higher cost. I know that sometimes when doing it, it can take a moment for the rest of the folders to kick back in. Also then you can’t make folders under the Inbox folder, you have to make it in a different folder and drag it out. Mohit is a Microsoft Certified expert for all things Microsoft.

That’s why, here I am to help you in this situation by providing you with solutions. But, before that, let’s understand the cause of the issue. If I am sitting on my inbox and do a send/receive, no new mail will populate. The send and receive does not error, it looks to complete successfully. Doing a send and receive does not update the mail, and I have played with all kinds of settings in the send and receive groups but nothing seems to work.

Outlook not syncing IMAP emails

I still have to manually click on a different folder other than inbox, then click back to inbox for new items to appear. Microsoft, gmail and other popular accounts should sync automatically, but if they don't, I'm inclined to think it's due to the VPN or a security/antivirus app that is scanning the TB profile folder. A stable connection between your email client and email server depends on the syncing of your IMAP folder. If the server is down and you are experiencing issues, the problem IMAP folder is not syncing occurs. So, check the status of your IMAP server follow the steps below.
